Magnetic-Free Twin-Coil Expertise Offers Excessive Decision, Precision and Reliability for Motor Place Sensors Utilized in Robotics, Industrial and Medical Units
Renesas Electronics Company (TSE:6723), a premier provider of superior semiconductor options, as we speak introduced an inductive place sensor (IPS) know-how for extremely correct motor place sensor ICs for robotics, industrial and medical functions. Using non-contact coil sensors, the place sensing know-how can exchange costly magnetic and optical encoders now generally utilized in motor management programs that require absolute place sensing, excessive velocity, accuracy and reliability.
The proprietary IPS know-how from Renesas makes use of sensing components consisting of copper coils etched on a printed circuit board (PCB) to detect the place of a metallic goal. In contrast to heavy magnet-based sensors, the IPS merchandise can function at 600 Krpm (electrical) and detect the place proper at startup, whereas the propagation delay is lower than 2μs, making them superb for motors with excessive rotational speeds. Furthermore, the sensor know-how helps auto-calibration and linearization options, making certain constant efficiency all through a motor’s operational life.
Based mostly on the Vernier precept, the dual-coil sensor know-how helps a decision of as much as 19 bits and an accuracy of as much as 14 bits, which makes them superior to comparable merchandise out there out there. The sturdy sensor know-how will function reliably in harsh environments, the place they are often uncovered to excessive temperatures, mud, moisture, vibration and electromagnetic interference (EMI). The induction sensors are proof against stray fields, require no upkeep, and are much less inclined to error than magnetic sensors. These benefits make induction place sensors a extra engaging choice than standard optical encoders or magnetic-based encoders, which are typically heavier and costly.
“Our induction place sensor know-how represents a big leap ahead in motor place sensors,” mentioned Jan Leuckfeld, Senior Director, HPC Analog (Sensor) Division at Renesas. “They’ll allow us to supply differentiated motor place sensor ICs for industrial functions which are sturdy, extremely correct and cost-effective.”
“Place sensors for manufacturing facility flooring should endure excessive circumstances akin to humidity, excessive temperatures and vibration,” mentioned Ulrich Marl, Key Account Supervisor at Lenord+Bauer, a Renesas buyer and a number one producer of encoders for industrial programs. “By means of our collaboration with Renesas, we have built-in IPS-based know-how into our encoder portfolio to make sure reliability and security, whereas decreasing downtime in essential functions.”
The induction place sensor know-how will help generally used UART, ABI and I²C communications interfaces, making certain a seamless integration into industrial networks and facilitating real-time monitoring and information evaluation. Moreover, the brand new sensor know-how can be backed by an entire toolchain that features devoted software program for person customization and precision optimization. Renesas plans to mix the brand new sensor with quite a few appropriate units from its portfolio to supply a big selection of Successful Combos. These Successful Combos work collectively seamlessly to carry an optimized, low-risk design for sooner time to market. Extra details about Successful Combos can be found at: renesas.com/win
